Kendrick Power Packs

Introducing our Brand New Lithium Iron Phosphate Power Packs!

Many times the useable capacity, but only a fraction of the weight. Features include:

  • USB Charging Ports
  • Bluetooth Battery Monitoring as well as a dedicated display that shows rate of power draw (or incoming charge), remaining capacity, and voltage.    
  • 4,000 Cycle Battery Lifespan. And even then, it still holds 80% of its original capacity.
  • Flat Voltage Curve. Even when drawing a heavy load, voltage remains constant
  • A "smart BMS" that protects the battery from over current, and over/under temperature.
  •  
    For answers to Frequently Asked Questions see the Kendrick Power Pack FAQ Sheet.

    Shipping for Batteries
    Battery products are not covered by our standard "flat rate" shipping. Extra shipping charges vary based on size and weight and you will see that in your shopping cart during checkout. Power Packs and replacement batteries will only be shipped ground service. For US and Canada orders, shipping is by Canada Post/US Postal Service.

    Kendrick Power Packs NEW (June 2017) 7 new models! Now with optional Anderson Power Pole plugs!

    For decades, Kendrick Power Packs have been the Gold Standard for rugged and reliable portable power. With proper care, these packs will last many years and when the battery reaches the ripe age of retirement, just pop-in a replacement and you're good for many more years.

    All models have the traditional cigarette lighter socket and now, Anderson Power Pole connectors are available.

    Our Premier Power Packs can also be configured with STEP-UP Voltage Inverters to power mounts that need 15V / 18V / 24V / 48V. Inverter output uses a 3-prong "XLR" connector to prevent accidentally plugging into the wrong outlet. We offer a variety of telescope power cords that will work for your mount.

    All wiring connections use proper gauge wire and are soldered (the battery terminal connections excepted). Our Premier Series uses Schurter circuit breakers, so there is no need to carry extra fuses. Our Premier Series use all metal, powder coated cases.

    All models include a Deltran battery float charger. The included charger will never overcharge your battery and may be left plugged into the battery for extended periods of time without harming the battery.

    All models also include a tough padded cordura carry bag. The carry bags have a pocket to store the charger when not in use.

    Our Premier Series Power Packs are designed for easy battery replacement.

    50AH Preimier Lithium Iron Phosphate Power Packs

    What Makes a Kendrick Lithium Battery So Different?

    In 2 words or less… capacity and amperage.

    Kendrick Power Packs are purpose designed to deliver 12V and almost all astronomy equipment was designed to run from a 12V car battery. BUT now we have cooled CMOS Cameras, Dew Heaters, and Laptops to power, and those devices need more than just 12V, they also need high current (amps) and that is where most lithium power packs fail miserably. A lot of the lithium power packs are really just a rebranded consumer product design to charge you cell phone. Some even have fairly capable 120V inverters, but the 12V power output on many of these units simply can’t deliver enough amps. A Kendrick Lithium Iron Phosphate Power Pack can deliver up to 50 amps of 12V power.

    Dual Battery Monitors

    Our Premier Lithium Power Packs feature:

  • Dual USB Charging Ports
  • Precise Battery Monitor. This is a highly accurate "shunt" based battery monitor that tracks outgoing and incoming (charger) current. The status display shows voltage, current (amps) rate of charge/discharge, percent power remaining.
  • Bluetooth Battery Monitoring. Your smartphone/tablet can be used as a remote battery monitor using a free iOS or Android app
  • Cigarette Socket(s) with permanently attached plastic caps that will flip closed to keep dirt out of the jacks when not in use.
  • Anderson Power Pole Outputs (4 circuits in total) with 30 amp contacts
  • 25 amp, 10 amp, and 5 amp circuit breakers on all power outputs.
  • Optional Step-Up Voltage Inverter uses a 3-prong "XLR" connector to safeguard against plugging into the wrong output. Telescope Power Cords are availble for popular mounts.
  • Inverter output is a three pin XLR Connector (requires purchase of a Telescope Power Cable)
  • The cordura carry bags have a couple of bult in pockets to accomodate various batttery accessories, such as cables or the charger.
  • 10 Amp Charger.
  • Rugged Steel Enclosure
  • Weight: 15.4 lbs.(7.0 kg)
  • Dimensions: 8.25”L x 5.5” W x 9.25” H
  • These Power Packs have the muscle to meet the demands of the modern amateur astronomer / imager. They are rugged, beautifully made and dependable. With proper care they have an "unlimited" lifespan and never require a battery replacement.

    How does a Kendrick Lithium Iron Phosphate Power Pack Compare to other "astro-brand" Lithium Power Packs? Well, for starters, this is NOT a "white-labeled" consumer gadget. These are custom made, purpose designed for astrononmers that need sustained power over long periods of time. You should always do your own research, but some of the products you find are not really a 12V battery. Some are really a 5V battery with an electronic component that tries to boost voltage. Quite often, the current (amps) is not enough to power CCD/CMOS Cameras and Dew Control systems. By comparrison, the Kendrick Lithium Power Pack is native 12V and can output as much as a sustained 50 amps.

    AC Inverter Solution

    Can support AC Inverters up to 300W. Do you need 110VAC to run a laptop? Simply connect an AC Inverter.

    Please be aware that Premier Power Pack models with a built-in inverter will require the purchase of one of our Kendrick Telescope Power Cables to match your mount.

    3 times the useable power but only a fraction of the weight!

    That's right. Comparred to our famous 33Ah Power Packs, the usable power is 3 times more, but weight less than half. The new Lithium models have the identical physical dimensions, yet they weigh far less.

    Charging Your Battery

    IMPORTANT NOTE: Do not discharge your Kendrick battery below 11.6 volts as it may be damaged internally. When charging the battery, be sure to plug the charger into the battery first, then into a wall socket. Failure to do this will result in the battery failing to charge.

    The charger will never overcharge the battery and may be left plugged into the battery for extended periods of time without harming the battery. We have a 6 amp float charger available that will charge the 2082 and 2083 family of batteries in 5 to 6 hours (not recomended for the 2081 or 2080 batteries). Customers outside of North America will need to choose a battery charger with a plug that is appropriate for their country (see the shopping cart below).

    NEVER use an automotive charger to charge these batteries. It will ruin the battery. Automotive chargers charge at a higher voltage than other battery chargers. If the charger charges at 14.8 volts or higher, the electrolyte will begin to turn to gas and ruin the battery. In a normal car battery this is not a problem as the battery can be topped up. In a sealed battery (which ours is) the electrolyte that turns to gas will be vented through its seals and cannot be replaced."

    A Note About Deep Cycle Batteries And Low Voltage Cut-Off

     

    Warranty

    Customers are strongly encouraged to inspect and test their battery immediately upon receipt. Check to make sure it is fully charged, that the LED display works correctly, that the charger works properly.Also, be sure to continue to check the voltage for several days after receiving it. It should hold its voltage. If it does not, contact Kendrick.

    The battery is under warranty for three months from date of shipping. The rest of the battery pack is under warranty for 6 months after the date of purchase. Consequential damages for malfunctions, resulting from accident, misuse, abuse, failure to follow operating instruction, or unauthorized repairs will void this warranty.

    Every battery is shipped in a heavy duty shipping box. Customers are requested to keep this box for the warranty period in case the battery should ever need to be returned for maintenance or warranty replacement. BATTERIES MUST BE RETURNED IN THEIR ORIGINAL SHIPPING BOX FOR WARRANTY REPAIRS/REPLACEMENT. Warranties for batteries will only be honored on batteries shipped in their original packaging.
